The philosophy behind the FFPAMRA is to create an altimeter that is both flexible to the users' needs and still "field-proof". The hobby of model rocketry is made up of very smart people, so they ...

const int chipSelect = 4; //SDCARD_SS_PIN – Change to “28” if using an MKR Zero Board; bool write2SDCard = true; // Will write to SD card if true. float triggerAltitude = 10.0; // Arduino will only ...

While traditionally a project geared more toward the model rocket crowd, a lot of people are flying quadcopters these days, and knowing the altitude your RC aircraft reached is a nice thing to know.
